Abstract: A mobile device supports loading application-specific interfaces associated with the third-party application into a social networking application. The mobile device sends a third-party application identifier to a remote server, which returns a verification result. If positive, the mobile device activates the third-party application to generate an application-specific interface and loads the interface into the social networking application. After detecting a user request initiated through the interface, the mobile device sends the user request to the remote server, which performs a transaction with a third-party server accordingly and returns a response to the mobile device. In response, the mobile device deactivates the third-party application and replaces the application-specific interface with a display of an instant message corresponding to the response in the social networking application.
